The alert unit is characterized by performing the blinking light emission.

According to the information display device of the present invention, since the display unit including the information display unit that performs character display and the alerting unit that performs graphic display is incorporated in the main body case, the information display and the alerting are integrated. It is possible to read the information by letting the line of sight induced by the flashing light emission of the alerting part naturally face the information display part.
In addition, when the character display of the information display unit is vertical writing, the position is adjacent above the first character, and when the character display of the information display unit is horizontal writing, the position is adjacent to the side of the first character. In the above, the attention calling part emits flashing light, so that the line of sight induced by the flashing light emission of the attention calling part is naturally directed to the first character of the character display, and the information is read so as to flow, thereby improving the information transmission be able to.

  In addition, when the character display of the information display unit is vertical writing, the height of one character of the character display is compared with the width of one character of the character display when the character display of the information display unit is horizontal writing. If a gap of 0.8 times or less is provided between the previous period information display part and the previous period alert part, the information display part and the alert point part can be felt more integrally. The line of sight induced by the flashing light emission of the alerting part naturally goes to the information display part and can read the information.

  According to the information display device of the present invention, the line of sight induced by flashing light emission for alerting can be naturally directed to the character information display, and the information can be read more reliably.

Embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of an information display device according to the present invention, and FIG. 2 is an enlarged view of a main part of the front view of FIG.

In the drawings, reference numeral 1 denotes a main body case of the information display device. The main body case 1 has a frame body formed by framed with left and right vertical frame bodies 11 and upper and lower horizontal frame bodies 12 made of an extruded shape member made of aluminum, and a back plate formed of an aluminum plate painted on the back side thereof Is attached and is formed in a box shape with an open front surface.
A protective cover 2 formed of a translucent polycarbonate plate is attached to the front side of the main body case 1 so as to close the opening.
Inside the main body case 1, a display unit 31 in which LEDs 3 are arranged in a dot matrix on a wiring board and information such as characters and symbols can be variably emitted and displayed is incorporated, and information displayed on the display unit 31 is displayed. The protective cover 2 is permeated so that light can be emitted outside the main body case 1.

4 is a control box. The control box 4 stores the electric power generated by the solar cell 5 in the internal storage battery, and uses it for light emission of the LED 3, and controls the information display pattern of the display unit 31. The control box 4 includes a control unit that adjusts the brightness of the LED 3 that emits light.
In this embodiment, the electric power generated by the solar cell 5 is used for the light emission of the LED 3, but other power sources such as a commercial power source may be used. Moreover, in this embodiment, the main body 1, the control box 4, and the solar cell 5 are each attached to the same support | pillar 6.

FIG. 2 is an enlarged view of a main part from the front view of FIG.
In the present embodiment, the information display device is installed vertically, and a plurality of wiring boards in which LEDs 3 are arranged in a dot matrix of 24 dots by 24 dots are provided in the vertical direction to form the display unit 31.
The display unit 31 is provided with an alerting unit 33 in the upper part of the display unit 31 for blinking display so that two circular circles positioned in the lateral direction appear alternately by selective light emission of the LED 3, from the top to the bottom. An information display unit 32 that displays characters in the vertical direction so as to read the image is provided adjacent to the alerting unit 33.
By causing the LED 3 to blink and display in two circular shapes in the alerting unit 33, a driver or the like can easily notice the light emission of the LED 3 of the display unit 31, and the line of sight can be easily drawn.
The information display unit 32 displays characters, numbers, symbols, etc., and transmits necessary information to the driver.

  In the present embodiment, the alerting unit 33 is provided above the information display unit 32, which corresponds to a position adjacent to the first character of the character information displayed vertically so as to read from top to bottom. By performing blinking light emission of the alerting unit 33 at such a position, the line of sight attracted to the alerting unit 33 moves to the first character of the character information as it is, and the line of sight moves to flow, and the information display unit 32 Since the character display is read, the information transmission of the information display unit 32 can be improved. The same effect can be obtained even when the flashing light emission of the alerting portion 33 is performed on the left side of the character information displayed in the horizontal direction so as to read from left to right. In the present embodiment, the information display unit 32 is formed so as to be able to display four-character information. However, when the number of characters represented in this way is small, the position adjacent to the last character as well as the position adjacent to the first character. It is also effective to use flashing alert light to direct attention to the entire text information.

  Further, in the present embodiment, the attention calling unit 33 is blinked so that two circles arranged in the horizontal direction alternately appear. When a driver or the like visually recognizes the information display device from a relatively short distance, It is easy to recognize the difference in the circular position and attract attention. When a driver or the like visually recognizes an information display device from a relatively long distance, the difference between the positions of the two circles arranged in the horizontal direction seems to be small and this effect tends to decrease, but the two circles appear simultaneously. The attractiveness can be enhanced by changing the light emission pattern such as flashing light.

  In this embodiment, the LEDs 3 arranged in a dot matrix are selectively made to emit light and two circular shapes are displayed by the alerting unit 33. However, the present invention is not limited to this, and the LEDs 3 are preliminarily formed into two circular shapes. May be arranged. Further, a lens body may be provided on the front surface of the LED 3 that flashes and emits light by the alerting unit 33, and the light emitted from the LED 3 may be refracted and concentrated to adjust the intensity of the light emitted forward.

The information display device of this embodiment is provided with the alerting unit 33 so as to be adjacent to the information display unit 32. However, when the gap between the information display unit 32 and the alerting unit 33 becomes large, the alerting unit 33 is attracted. The gaze of a driver or the like does not go toward the character display on the information display unit 32, and the original effect of reading the information displayed on the information display unit 32 may be small. Further, when the gap between the information display unit 32 and the alerting unit 33 is reduced, the presence of the character display on the information display unit 32 is canceled by the flashing light emission of the alerting point unit 33, and the character display on the information display unit 32 is displayed. There is a risk of not reading.
For this reason, it is preferable to provide an appropriate gap between the alerting unit 33 and the information display unit 32.
In the information display device of this embodiment, when the gap between the alerting unit 33 and the information display unit 32 is changed and the readability of the character display of the information display unit 32 is confirmed, the gap is the information display unit 32. When the height L of one character to be displayed is not less than 0.9 times the height L, the alerting unit 33 and the information display unit 32 are not felt together, and the line of sight is not easily directed to the character display of the information display unit 32. It was confirmed that Further, when the gap is 0.1 times or less the height L of one character, the line of sight remains drawn to the alerting portion 33 and an attempt is made to read the first character of the character display on the information display portion 32. It was confirmed that the tendency to disappear became stronger. For this reason, the size of the gap between the alerting portion 33 and the information display portion 32 is preferably 0.8 times or less, and 0.1 times or more the height L of one character of the information display portion 32. It is preferable that Furthermore, when the conditions were changed and the readability of the character display of the information display part 32 was confirmed, the clearance between the alerting part 33 and the information display part 32 is 0.2 times the height L of one character. It was confirmed that the value is more preferably 0.4 times or less and the character display can be read appropriately.

In the information display device of this embodiment, the information display unit 32 and the alerting unit 33 are lit and displayed both during the day and at night. However, the information display device is easy to visually recognize during the day for drivers and the like. When flashing the alerting part 33 at night with the light of light, attention is directed only to the alerting point part 33 by making it feel dazzling, the line of sight does not flow to the information display part 32, and the character display is read The original effect may be small.
For this reason, it is preferable to change the light intensity of the alerting unit 33 between the daytime and the nighttime, and to make the light intensity weaker than the daytime during the nighttime.
In the information display device of this embodiment, when the visibility of the LED 3 that performs flashing light emission of the alerting unit 33 is changed and the visibility is confirmed, the nighttime luminance is set to about 20% of the daytime. Thus, it was confirmed that the flashing light emission of the alerting unit 33 at night was not felt dazzling and the character display of the information display unit 32 could be read appropriately.

In addition, by changing the luminance of the LED 3 that performs flashing light emission in the alerting unit 33 between the daytime and the nighttime as described above, an effect of causing the nighttime alert flashing light emission 33 to be favorably visually recognized is provided in the alerting unit 33. This can be achieved by changing the size of the two circles to be displayed.
The information display device of this embodiment did not change the brightness of the LED 3 during the daytime and nighttime, and when the visibility was confirmed by changing the size of the two circles, the diameter of the nighttime circle was compared with that during the daytime. It was confirmed that the blinking light emission of the night alert section 33 was not dazzled and the character display on the information display section 32 could be read appropriately by setting it to about 60%.

In the information display device according to the present embodiment, the information display unit 32 and the alerting unit 33 are lit and displayed at adjacent positions, but the light intensity of the alerting unit 33 is about the same as that of the information display unit 32. The flashing light emission of the alerting unit 33 is less noticeable than the information display unit 33, and the original effect of inviting the driver's attention may be reduced.
For this reason, it is preferable that the alerting unit 33 emits light with a stronger light than the information display unit 32.
In the information display device of the present embodiment, when the brightness of the LED 3 that performs flashing light emission of the alerting unit 33 is changed and the visibility is confirmed, the brightness of the LED 3 that performs character display of the information display unit 32 is five times higher. It was confirmed that by flashing and emitting light at a moderate brightness, the attractiveness of the alerting portion 33 can be improved and the character display of the information display portion 32 can be read appropriately.

Further, the blinking period of the alerting portion 33 is also an important factor in the driver's gaze guidance. Since the surroundings of the information display device are bright during the day, shortening the blinking cycle and performing fast blinking makes it more noticeable and makes it easier for the driver to draw attention. However, if the flashing light is emitted at the same cycle at night, the surrounding light is dark and the flashing light emission becomes more clearly visible, which makes the driver feel bothersome and attracts attention. The original effect of reading the display may be small.
For this reason, it is preferable that the blinking cycle of the alerting unit 33 is longer than the daytime.
In the information display device of the present embodiment, when the visibility of the flashing cycle of the alerting unit 33 is changed and the visibility is confirmed, the flashing cycle is about 1.5 times longer than the flashing cycle during the daytime. As a result, it has been confirmed that the driver can improve the attractiveness of the alerting unit 33 without feeling bothersome and can read the character display of the information display unit 32 suitably.
